When i got my 06' VLX last fall the only thing i was worried about was that it didn't have a depth finder. Running on the river where i normally run it is important to me to have a depth reading because of shallow areas, etc. I was hoping to keep my dash as stock as possible and didn't want to make another hole somewhere for an auxiliary depth system. When the dash turns on at startup it would show depth along with the air and lake temp, so i figured i could somehow get it to show there. I started looking around and got in contact with bakes online and saw that they had the module for an 04-06 malibu so i figured if i picked that up and added the transducer i would be good to go. Obviously not the cheapest route, but i liked the idea of it integrated in the dash like the stock system. Only problem i ran into was that they no longer make the transducer for these boats as i'm sure plenty of others with these year boats that have found out if their transducers failed. After talking with Andrew at bakes he got me a pdf and info that there was a lowrance transducer that was supposed to work in place of the discontinued transducer. Basically you cut the plug off the old transducer and splice it on the new one because the new transducer plug is different than the old one. However since i didn't have an old one to replace, i tried to get a failed one from another malibu owner. After not having any luck going that route, i decided i could just make up my own plug. I got some weather pac pins that i could make fit and ended up making a crude plug out of silicone but it works. I set the depth finder on the top of a 30 gallon barrel filled with water and the depth read 2.5 ft, which according to my math is equal to the 30" that the barrel measures. I ended up mounting the transducer where i had seen it mounted in other vdrives
The new lowrance transducer is a: Lowrance PD-WBL. I have a pdf from andrew that shows how to use this replacement transducer that i can try to send others if needed, or else i can get it to Rugger to put in the resources section for others if needed. Last thing to do is get this boat on the water to make sure it all reads as it should. I'm not sure if i have explained this very well, so if you have any questions let me know and i'll be happy to help, or send you the pdf or whatnot.
